标准的注射机可用于生产多种薄壁制品。目前新型注射机的性能大大超过了 10 年以前。材料、浇口技术以及设计的进步，进一步拓宽了标准注射机对薄壁制件充模的性能。但由于壁厚不断减少，需要一种更特殊的、具有高速和高压性能的注射机。
Standard injection machines can be used to produce a variety of thin-walled products. At present, the performance of the new injection machine is much better than that of 10 years ago. Advances in materials, gate technology and design have further broadened the performance of standard injection machines for filling thin-walled parts. However, due to the decreasing wall thickness, a more special injection machine with high speed and high pressure performance is needed.
例如，一个厚度小于 1mm 的电子制件，充模时间小于 0.5 秒且注塑压力超过 210MPa 是很正常的。用于薄壁注塑的液压式注射机设计有储压器，可频繁地驱动注塑和合模。
For example, it is normal for an electronic part less than 1 mm in thickness to have a filling time of less than 0.5 seconds and an injection pressure of more than 210 MPa. Hydraulic injection machines for thin-wall injection moulding are designed with pressure accumulators, which can drive injection moulding and clamping frequently.
